features such as rivers, section lines, streets, etc. to encompass all of the delineated 10 year capture zone boundaries. The 10 year capture zone boundaries depict areas in which stormwater that falls on the ground has the ability to infiltrate through the ground to reach the aquifer that the wellhead is located in within 10 years or less. The 10 year capture zone is therefore the more critical and realistic boundary that should be used for limiting infiltration practices to protect the City's wellheads versus the DWSMA boundary. Timeframe: This case is estimated to conclude in 15 minutes. Observations /Alternatives: Attached is a draft of City staff's proposed modifications to the City's stormwater management permits, plans, and ordinances. The modifications were presented to the Public Works Committee of the City Council at the June 17, 2014 meeting. The Public Works Committee recommended moving forward with the ordinance revisions. Also attached is a figure showing the City's west DWSMA and associated delineated 10 -year capture zones around all public water supply wells within the west DWSMA. As can be seen, numerous ponds and wetlands exist within the west DWSMA and will be impacted by the outcome of this case. Note that in 2013, there were amendments to the Stormwater Pollution Control ordinance and while those amendments are now effective, they have yet to be codefied online through MuniCode. Thus, there are some numbering differences between the attached redlined version and the draft ordinance. City Staff continues to review and where need be reconcile formatting and numbering of the draft ordinance for accuracy; however, the content of the amendments will not be affected. Funding Source: No funding is required for this case at this time. However, if Council approves the proposed language modifications there will be minor costs associated with republishing the modified stormwater management permits, plans, and ordinances. However, these costs will be paid through the Stormwater Fund. Recommendation: City Staff recommends approval of Ordinance #14-09 amending City Code Chapter 117, Article II, Division 6 - Performance Standards, Subdivision II. - Stormwater Pollution Control. Action: Motion to recommend that the City Council adopt Ordinance #14-09 amending City Code Section 117, Article II, Division 6 - Performance Standards, Subdivision II. - Stormwater Pollution Control.
